I have just had a new computer as my last one kinda died on me, but my floopy drive is being a bit awkward.  Quite often i put a floppy disk in the drive and it says 'Disks needs formatting' now these are disks that i've used before and have stuff on them.  I recent;y borowed a Sony mvc-fd75 digi cam, with the thought to buying it, i formatted a disk at request and then took a couple of practice shots with the camera (one of these old ones that copies the taken picture onto disk) put it into the drive to view the pics and it comes up with this disk is not formatted - any ideas?

1. Your new drive is simply faulty.  Does it format a disk, and if so does it then work OK? Can you copy files to it? If so, then:
2.  The heads on your old floppy were out of alignment.  The heads on all floppy drives are cailbrated to be in EXACTLY the same place over the diskette for each track.  So, when a disk is recorded in one drive, and inserted into a different drive, the heads move to EXACTLY the same place on the disk.  The recorded data is directly undernetah the head, so that it can be read.

If the data is not directly underneath the head of the new drive (it only needs to be a few thousandths of an inch out), it cannot read the data - Windows beleives it is not formatted - prompts you to format.

3. The heads on your new drive are out of alignment, and the old drive was OK.  

The practical way to diagnose is to use brand new, pre-formatted disks and see which drive they work in.  

Alternatively, format a floppy in the new drive, and try it in at least 3 other drives.  See how many read it.  Then, format a disk in your old drive and see how many other drives read it.
